         * 1. An array of arrays with 2 values. In this case, the numerical values will
         *    be interpreted as `y, z` options. Example:
         *    ```js
         *    data: [
         *        [40, 75],
         *        [50, 50],

         *    ]
         *    ```
         *
         * 2. An array of objects with named values. The following snippet shows only a
         *    few settings, see the complete options set below. If the total number of
         *    data points exceeds the series'
         *    [turboThreshold](#series.variablepie.turboThreshold), this option is not
         *    available.

         *        z: 4,
